il all whom it may concern:

lle it known that I, WILLIAM N. SPRINGER, u citizen of the United States, and e resident of South Bend, in the county of St. Joseph end State of Indiana, have invented eel-loin new nd useful Improvements 1n Engine (iru!igl)lm\'s; and l do hereby dechire the following to be a full, clear, and enact description of the invention, such es will enable Others skilled in the art 'to which it appertains to make and use the salue.

This invention relates to improvements in plows,-the sanne being o division of application for patentiled by me on the seventh day of January 1915, and designated by Serial No. l,()0,-the invention in the pre:- ent application relatingmore particularly to means for reis-ing and loweringl the plow structure for purposes of adjustment.

Une object of the invention is to provide efficient. means which may be employed in conjunction with power lift mechanism, for manually adjusting the plows.

A further object is to so constructand nrra nge said adjusting means that the plows muy be leveled or adjusted for depth of plowing'.

With these and other objects in view, the invention consists' in certain novel features of construction and combinations of parts as hereinafter' set forth and pointed out in the claims.

: ernbly two or three), but in the drawings I have shown three plow units and will describe the structure :Ls thus constituted.

l., 2, 3 represent the beams of the plow units, end these are bent downwardly at their rear ends to form standards 4 having 'plow bodies 5 suit-ably secured thereto. The

several plow units are arranged in diagl enel formation, as is usuel with gang plows. .lhe beam l of the forward plow unit is rigidly connected with the beam of the central beam 2 by means of a spread r brace 5 the central beam by means of a spacer brace 7 clamped to said beams near their rear ends, the beam 3 terminates at vits forward end, rearwardly of forward ends of the Patented June 20, 1916. 4

beams l and 2 and is connected with the n central beam by means of a spacer brace S, the latter being extended forwardly from the forward end of the beam 3 to form aun arm or extension 9 for said beam and terminotes in horizontal alinement with the for ward ends of the beams l and 2. A draft bar l0 is rigidly connected with the for.- word ends of the beams 1 and 2 and the forward end of the arm or extension 9, b means of couplings 11. Links 12 are edi justzibly connected with the draft bnr, end to these links, other links 13 are connected by break pins 14. Draft devices, such as chains l5, are connected at one end with the links 13, and et their other ends, seid chains are adapted for connection withe l over the several beams and mounted in bearings 17 secured thereto, the cranked outer end of said axle being,r disposed at the left hand side of the structure sind suitably mounted in the hub of a ground wheel 18.

Brackets 19e-20 are rigidly connected with and project above the forward ook tions of the beams of the outer plow units (the bracket. if() being secured to the extension 9 of benin il, when three plow units are employed), and to each of these fixed breekets, two vertical guide bars 21 are 'gidly secured means of set screws 22. F1V cally movable slide brackets 223-24l are dis posed near the respective fixed brackets l9-20 and are provided with perforated en lzirgements 25 mounted` on the guide bars 2l. The vertical slide brackets 23--24 are mode with elongated slots 26, through which a forward axle 27 passes, said axle having :i journal or spindle bearing inthe hub of a forward ground wheel 2.8 at the right hand side of the structure. The axle 27 rmay be square in cross section, except et its journal or spindle end, and .Where said axle passes through the vertical slots of the slide brackets, sleeves 29 may be mounted thereon and disposed in Said .slots .so as to he eapahle otl turning therein.

The slide hrarlt'ets '53 24 are provided. at their lower ends with eurved flanges ll and ahove the elongated .slots 2V. rollers l are mounted. lwtween the rollers 3l and the llanges Itl. eams 53;' arel seeured to the axle 2T. said eams normally engaging the rollers. and thus.l the forward portion ol' the plow structure is normally. supported on the axle the latter heilig supported at one side of tht. .strueture hy the ground wheel 2H. Ilhe. other side of the plow strueture is .supported hy the wheel 1N in whil'h the erank axle ifi is mounted. means heing provided for normallyv loelt'ing .said eranlt axle against turning and for adjusting. as hereinafter partieularly deserihed. 'l'ht` rear end ofthe plow strueture is supported h v a trailing easter wheel 1335. the axle hraelt'et ill ol' whieh is mounted in a sleeve 155 ronneeted hy pivoted links' Ilt with a hraelt'et Iii' adiustahly lixed to the standard olV the rear plow unit il. The rear end of the plow strueture may he raised hy means ot' a manually operahle serew iix swiveled on the lixed luz-leitet lli' and threaded through an arm i'J made rigid with the sleeve 35, as shown in Fig'. l.

ltevertin; r now to the mountings between the plow .strueture and the forward axle "27, it will he ohserved that kthe t wo .slide liraeltets .I and l are eonneeted hy a rigid har or shaft l0. ,'l`his har orshaft is engaged by the .slotted ends ol' arms 41. the latter heing` rigidly seeured to a transverse shaft 4;! mounted in hearings lfl ofn the fixe l hraekets {ils-52H on the outer plow units. 'itll this arrangement of parts. any vertieal movement of one of the .slide luaeltets will he imparted to the other. and the neeessity for providing separate vertieal adjusting means for eael-l slide liraeltet '.f' fil will he oliviated. 'l`he,vertieal guide hars 2l for the 'slide luaeket l. are, eonueeted attheir upper ends h v a cross head ll having a perforativn l5 in whieh the upper portion of a threaded rod 4G is swiveled. said threaded rod passing through athreaded hole 47 at the upper end of the slide hraeket '24. and at the upper end of said threaded rod` a manually operable handh` LQ is seeured. Tt. is apparent that hy operating this handle to tarn the threaded rod il?. the guides Q1 and the plow structure to whieh they are se. eared. will be moved verticallyv relatively tov the slide ln'aeltetse-sa y Vfs de. brackets being suppmted on Vthe .f "nti 16.27 and ground wheel as previousl aimed. and thnfs the plow units nr raised or A bracket- 49, having a shape approximately that of a hell-erank lever is iiosely mounted on the main horizontal portion of the eranh axle lll. and in the hil'ureated free, end ol' its lower arm. a nut 5H is pivotally mounted. The threaded rear end of a rod or pitmau .'1 passes through the nut 3f?. and the forward threaded end of .said rod or pitman is :uliustahl'y eonnerted with a sleeve 5'. pi\oted lo a head filnwthe latter heing rigidly .seenred to the lelt hand end oil the front axle 'Ji'. The upper arm oll the helleran'it' lf' is hil'urrated and Carries a pivoted Sleeve 5l in whit-'h a, threaded rod is syviveled. 'l'he upper end ol' this rod is provided with an operating handle 33" and its ythreaded portion passes through a nut 5V pivotally mounted in the hit'nreated free end of an arm 5T. whieh lattea" is seeurel \"l:astened to the arm of the erank axle hy meansl of a elamp 5S.' lt is apparent that hy operating the threaded rod I. the eranh axle will he turned so as to move the ground wheel forwardly or l'irnltwvardlv land thus raise or lower the .side of the plow strueture at whieh .said wheel is lorated. ly means' of these deviees also. thtv gang of plows may lu :ttt'lll'ately itvt'lt'il.

'l'he slide hraeltet '.il is provided near its iower portion with laterally proieeting arms tl'ymtl. To the arm (1C. the lower end fol a lever HN is pivoted. and to the arm (i7. a lever Gil is pivoted at a point hetween its ends. the upper portionsol'saidlevfersheing eonneeled liy a rod or har 7() pivoted at its reispeetive ends thereto.

The. lever t(i9 projeets upwardl)l above the tlf) connecting rod end has a rope 76 attached thereto, said rope being extenffled to the tractor Within convenient reach of the olierntor.

When the operator desires to cause the glows to be miseri automatically by power derivar/4l from the forward gronnri wheel 2S, he will pull the, rod 76 and thus shift the hm lovers 68 and on. Bv this manipuletion of said levere, the roller Il or lever 68 will be moved ont of the recess S4 of cani plate 6l and away from the tail of the flog; G2, thun permitting the spring 65 to more anni log to engage the ratchet Wheel oil. #he 'plow nioree' forwardly, :motion Will be imparted hy the mteliet wheel 6G and dogg' fft to he man pirate 6l, the axle 2T sind the zi the l zitter, cooperating with the i on (he, slide brackets QS-MZL, will i f 'er to rifle.
